This is an extruder-upgrade for the printers like CR-7, CR-10, Ender 2, Ender 3.
The PTFE insert is held by an additional extrusion. It closes the gap in the extruder that normally allows TPU to get jammed.
To optimize the function, you can also add a rubber on the steel-roll.
Works great with every flexible filament.
